4. Run power supply cable through the connector, leaving about 8” of
wire inside the box.
5. Connect the supply cable ground wire to green ground screw provided.
NOTE: Lead holes for a #8 sheet metal screw have been provided in the
sides of the back box.. After the finished wall or ceiling has been put up,
drive a # 8(m4) sheet metal screw (recommended 1” long) through the
side of the box not mounted to the stud. This will prevent the back box
from pulling out when installing the heater assembly. (See igure 1)
INSTALLATION OF BACK BOX
IN EXISTING CONSTRUCTION
(WALL OR CEILING)
1. Carefully mark and cut a hole measuring 9-3/8" (235mm) wide by 11-
1/8" (283mm) long. One edge of the hole must be cut along the
edge of a stud.
2. Proceed to No. 1 through 5 (Installation of Wall Box in New
Construction).
FIELD CONVERSION FOR LOWER WATTAGE RATING
NOTE: Refer to specification chart for lower wattage ratings which are
available.
To convert heater to lower wattage rating, completely remove red jumper
wire from both heating elements (See igure 2). Discard this jumper. Be
sure remaining wires are securely connected.
INSTALLATION AND WIRING
OF HEATER / FAN ASSE BLY
1. ollowing wiring diagram ( igure 3) connect supply wiring to heater
leadwires in back box.
NOTE: or 120 and 277 volt heaters connect the white neutral supply
lead to the heaters white pigtail lead, and connect the black supply lead
to the heater black pigtail lead. or 208 and 240 volt heaters change the
color of the heaters white pigtail lead to black by wrapping with black elec-
trical tape. (Most electrical codes require the supply leads to be con-
nected to black leads). Then connect the two black supply leads to the
two black receptacle leads.
GENERAL
The heater is designed for recessed installation in 2” X 4” (50mm X
101mm) stud or larger wall or ceiling sections using the wall box provid-
ed. The heater may also be surface mounted by using the Surface
Mounting rame, Model CWHSM or semi-recess mounted by using a
CWHS1 (for 1” (25 mm) recess frame) or a CWHS2 (for 2” (50mm) recess
frame). All three accessories are ordered separately. The heater may be
wired with standard building wire (60°C). Refer to specification chart (see
pg. 4) for correct supply voltage and wire size.
NOTE: The optimum mounting height for this heater is 18" to 24" (450 to
600mm) from floor to bottom of back box. Do not install closer than
4”(101mm) from the floor.
or surface or semi-recess mounting, consult Installation Instructions
packed with CWHSM, CWHS1, CWHS2.
INSTALLATION OF WALL BOX
IN NEW CONSTRUCTION
(WALL OR CEILING)
NOTE: If the finished wall surface is already up, follow instructions for
“INSTALLATION O BACK BOX IN EXISTING CONSTRUCTION”.
1. Determine which side of the back box is to be mounted against a
stud and bend the tabs at the rear corners out 90 degrees so that
the back box will be square with the stud after installation. (See
igure 1).
2. Remove one of the knockouts on socket side of the back box and
install a cable or conduit connector.
3. Position back box against side of studs and secure using nails or screws
as shown in igure 1.
NOTE: The back box must be installed with the front edge flush with
the finished surface.

7. It may be necessary to readjust thermostat a time or so until
exact comfort level is attained. Rotation in the clockwise
direction will increase the amount of time the heater will pro-
duce heat. Rotation in the counterclockwise direction will
reduce the amount of time the heater is on.
NOTE: or best results, the heater should be left “ON” constantly during
the heating season as the thermostat, when properly set, will maintain the
desired temperature.
AINTENANCE AND CLEANING
Your heater is designed for years of trouble-free operation and requires no
special maintenance other than occasional cleaning. The motor is perma-
nently lubricated.
Once each year, the heater should be cleaned to remove dust and other
foreign material which has collected during the heating season, as follows:
1. Turn power off at main switch.
2. Remove thermostat knob and grillle.
3. Use vacuum cleaner with brush attachment to remove dust and dirt
that has accumulated in heater (especially around element and fan
blade). Do not use water or any cleaners to clean heater compo-
nents.
4. Replace grille and thermostat knob.
5. Wipe grille clean with a damp cloth. DO NOT use waxes or any
cleaners that leave a residue since these may discolor during heater
operation.
6. Turn the main line switch on at the switch panel to restore power to
heater. The heater is now ready for another season of operation.
OPERATIONAL NOTICE
Your heater is equipped with an automatic reset high limit control that
will automatically turn the heater off to prevent a fire if the heater over-
heats. Should this occur, the indicator light will illuminate and will contin-
ue to shine until the limit resets.
THE ILLUMINATED INDICATOR LIGHT SIGNI IES THE HEATER
HAS BEEN SUBJECTED TO SOME ABNORMAL CONDITION.
CHECK HEATER TO INSURE THAT IT HAS NOT BEEN BLOCKED IN
ANY MANNER (I SO, REMOVE BLOCKAGE). I THERE IS NO
INDICATION O BLOCKAGE, IT IS RECOMMENDED THE HEATER
BE CHECKED BY A REPUTABLE ELECTRICIAN OR REPAIR SER-
VICE TO INSURE THE HEATER HAS NOT BEEN DAMAGED.
